Casing Centrializer

Bow spring centrializer:

Description:
Super-strength spring steel is applied to centralize casing in wellbore,and improve cementing quality.
Feature:
1、Every attachment is pressed into shape by moulding instead of welding and rivet.
2、3-section structure for easy transport.
3、Starting force and restoring force conform to API standards.
4、Easy-and-convenient to use.
5、Alternative turbulence plates can effectively improve displacement efficiency.
Specification:

Rigid centralizer:

Description:
It makes the casing centralized in wellbore and improves cementing quality.
Features:
1.Spiral blades increase annular turbulence.
2.With its stream-lined shape,it enables casing to run easily in wellbore.

Roller centralizer:

Integral centralizer:

Description:
Revolutionary centralizer design for highly deviated, horizontal ERD wells. One-piece integral unit has no weak point. It’s extremely robust and also tolerant to under gauge hole conditions.
Feature:
1. Integral steel plate     2. High temperature wire saw welding
3. Laser cutting         4. Bow centralizer be Hydroform
5. Heat treatment        6. Powder coating processing
PRODUCT SUPERIORITY
1. Processing technology of high precision meet the requirements of various size hole
2. Down, there is no initial resistance, low friction, low torque
3. Centered, enhanced string restoring force
4. Weak spot, high strength, no stress, high reliability
5. Without any separation of welding components or parts, eliminate the possibility of salvage
6. its elasticity can meet down into reducing interval
7. All the indexes exceed the standard API lifter
8. Article, straight centralizer design maximum casing running efficiency
9. Article, centralizer design and casing is a good joint, casing protection

Glider centralizer:

Description:
Spiral centralizer has a smooth angle between spiral righting slip and axis, is superior than conventional straight edge style: Firstly, when down into the hole and meet irregular borehole diameter there will be lateral component created on spiral centralizer by the wall of  hole which can reduce the resistance to impact; Secondly, There will be Swirl flow out of the centralizer when cement slurry through the spiral sheet, get smooth, washed wall virtual mud cake, Whirl flow length is 7-9m, the best distance is 3-4m near the centralizer nearby, which can improve the displacement efficiency of cement slurry, which is very beneficial for improving cementing quality.
